Rachel McAdams, 39, and Rachel Weisz, 48, have revealed that their sex scene in Disobedience created more energy and emotion on set than any of their heterosexual on-screen romps.

The couple star as lovers in upcoming film Disobedience, which focuses on religion and sexuality and is based on Naomi Alderman's controversial novel, the Daily Mail reports.

With the themes of sex and relationships central to the plot, McAdams and Wesiz revealed that filming their on-screen romp was like nothing they had ever experienced before.

McAdams reasoned that as two women working together they felt "safe and free" as she told EW: "There was energy to that scene that I haven't experienced in any other sex scenes [with men] in my career. There was camaraderie to it.

"All those things that you love about being a woman, you get to be with [in the scene], so I understand the attraction and appeal to that in a sexual context."

Weisz also lauded the "massively important and beautiful" scene as she explained that strict instructions from the director lead to a better end result.

She confessed: "You get in the bed and in my case it's always with men and you see what happens - it can come out a bit meaningless and generalized."

The pair also touched on the importance of working alongside women as they interviewed each other for Lena Dunham's online newsletter Lenny Letter.

Weisz reasoned: "As a woman, you're often the object of the man's desire, or he's the object of yours, but I felt like there was something just so different about the female gaze."

McAdams added: "Energetically, it was very different. We had great communication, and there was a very vulnerable, open, gentle, intelligent feeling to everything.

"We talked about the safety of it as well, doing a love scene. That was a very different love scene than I've ever done before, and it was the most kind of raw and vulnerable love-making scene I've ever done. And yet at the same time, I felt incredibly safe and cared for and free to explore."

In the movie, McAdams plays Esti - who returns to her Orthodox Jewish home after the death of her rabbi father but causes controversy when she rekindles a repressed romance with her best friend (Weisz).

Adding to the scandal, Weisz's character Ronit is married to McAdams cousin in the film.

Weisz is also producing the film, revealing last year that she is spending much of her time buying up rights to develop books into movies.
